FREE Oracle APEX Developing Web Applications Questions and Answers
You want to refer to a page by a name (or alias) instead of a page number in the application URL.
Which step most accurately helps you achieve this?
Explanation:
Setting an alphanumeric alias in the Page Alias attribute allows you to refer to a page by name (or alias) instead of its page number in the application URL. This makes the URL more readable and user-friendly.
David has created Page 10 as a form page using an Automatic Row Fetch process. A column named LOCATION has been added to the underlying table, and the form needs to include this new column. You decide to copy an existing page item :P10_DEPTNO and use that to represent the LOCATION column.
What is the minimum action required on the copied item to get the form working correctly?
Explanation:
By changing the source type to NULL, the copied item will no longer be bound to any specific data source. This allows it to be repurposed for the new LOCATION column without conflicting with the existing data binding.
Where is the Oracle APEX session state stored between calls from the browser?
Explanation:
Oracle APEX session state is typically stored in the browser in the form of cookies. These cookies maintain session information, allowing the application to maintain its state across multiple requests from the same user.
Which is a predefined authentication scheme in Oracle Application Express?
Explanation:
HTTP Header Variable is a predefined authentication scheme in Oracle Application Express. It allows authentication based on the value of an HTTP header variable sent with the HTTP request.
Which processing point is enabled for computations during page processing?
Explanation:
Computations during page processing are enabled at the "Processing" processing point. This point occurs after the page has been submitted but before any processing occurs, allowing computations to be performed before any other actions are taken.
Rick has created an ""editable"" interactive grid on a table that includes four audit columns: CREATED, CREATED_BY, UPDATED, and UPDATED_BY.
The four audit columns are included in the report with the read-only type set to Always.
How can Rick update all four audit columns when a user inserts a row, and the UPDATED and UPDATED_BY columns when a user updates a row?
Explanation:
Using "Enable" Dynamic Actions: Dynamic actions allow Rick to define actions that occur in response to specific events, such as row insertion or update in the interactive grid. By enabling dynamic actions, Rick can specify actions to update the audit columns accordingly when a user inserts or updates a row.
Jane is creating a new application. Users of the application will use SSO to authenticate. SSO has been defined for the instance.
Which step should Jane perform in the Create Application Wizard?
Explanation:
Selecting Single Sign-On (SSO) under Authentication in the Create Application Wizard ensures that users of the application will use SSO to authenticate, as per the defined SSO setup for the instance. This step configures the application to utilize the existing SSO mechanism for authentication.
John has a form page with an email item and a status item. What must John do to ensure that the email item is populated before users can enter any value into the status item on the form page?
Explanation:
By applying validation on the email item, John can ensure that the email field is populated before users can enter any value into the status item on the form page. This ensures that the required email field is filled out before proceeding to the next field, maintaining data integrity.
Which is true about a workspace in Oracle APEX?
Explanation:
In Oracle APEX, a workspace can be associated with multiple schemas within the same database. This allows developers to work with data from different schemas within the same workspace, providing flexibility in application development and management.
Which two actions can be done by a Page Process of type Automatic Row Processing (DML)?
Please select 2 correct answers
Explanation:
Apply a SQL WHERE clause to append to all generated INSERT, UPDATE, and DELETE statements at run time.
This statement isn't a capability of Automatic Row Processing (DML) specifically. Automatic Row Processing focuses on handling insert, update, and delete operations on individual rows efficiently without directly manipulating the generated SQL statements.
Invoke PL/SQL code to perform the inserts, updates, and deletes.
This option is correct. Automatic Row Processing (DML) can indeed invoke PL/SQL code to perform the inserts, updates, and deletes.
In Application Express, how do you enable a database schema assigned to the current workspace so that it can be used to serve ORDS-based RESTful Services?
Explanation:
This option directly addresses enabling a database schema assigned to the current workspace for serving ORDS-based RESTful services by registering the schema with ORDS. This step ensures that the schema can be utilized for RESTful service development within the workspace.
